[Flutter][3.22.0] fix accentColor & textTheme

[den0206]

fix two property

• accentColor(depracated) => Theme.of(context).colorScheme.secondary ref
• textTheme(depracated)

Fixed to build with Flutter 3.10.0.

Got this error with the fix, even with an "empty" NeumorphicApp() (using Flutter 3.10 and Dart3)

If someone is blocked with this and dont want to downgrade Flutter SDK, just use a MaterialApp for testing

The following assertion was thrown building NeumorphicApp(dirty):
Assertion failed:

colorScheme?.brightness == null || brightness == null || colorScheme!.brightness == brightness

The relevant error-causing widget was:

@thomasnappee
fix it, pls check wrap NeumorphicApp or MaterialApp.

[thomasnappee]

NeumorphicApp

Works perfectly 👍

@florent37 while the project doesn't seem to be actively maintained, could you please still take a look at this critical compatibility PR?

@florent37 while the project doesn't seem to be actively maintained, could you please still take a look at this critical compatibility PR?

Should this project be forked so that these issues can be fixed, otherwise this package is likely to die?

[lorriman]

A fork published on pub.dev means people willing to continue maintaining it.

For my own purposes I forked and then applied "dart fix" which did a fine job as far as I can see with no effort required from me. So now my project refers to my fork, and unless a graver and more difficult update is required, that should do for the foreseeable future.

@scttbloom, you can fork this project into your own repository, make the fix, for example using @den0206 changes then replace the pub.dev version of the package with you github version. An example of how to do this is in this link https://stackoverflow.com/questions/54022704/how-to-add-a-package-from-github-in-flutter.
